Specification of lLetters Patent.

'f 'Application led April 8, 41913. lSerial No. 759,604.

To zlZ whom it may concern Be 1t 4known that We, BENJAMIN P. SAUN- Dnns and OSCAR WVIUIAMS, citizens of the United States, residing'at Iatan and Weston,

Our. invention relates to improvementsI in.

apparatus for unloading freight cars, and our object 1s to provide novel means whereby poles, brush, etc., can be more quickly and economically unloaded than heretofore.

Ajfurther object is to provide an apparatus of this character, so'arranged that it can be quickly secured to or removed from' a freight car.

In order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which:

lii re 1 isa side elevation of a steel freigntcar provided with our unloading apparatus. "Figp2 is ja vertical cross section of the apparatus on line II--II' of Fig. 1, and showing the operation thereof by dotted lines. Fig. 3 is a cross section' of the apparatus on line I--II of-.Fig. 1, and showing the operation thereof by dotted lines. Fig. 4 isa broken plan view of one end of the freight car witha portion of the apparatus 1n position thereon. Fig. 5 is a cross -secti'on'of a modified form of apparatus Vappli'edzto a wooden freight car. ,4

1 designates a steel freight car of the ordi nary gondola type, embodying a body portion 2, trucks 3, and'sills 4 to reinforce the body portion 2.

In carrying out, our invention, we employ a plurality of standards 5 which extendl above the sides of the car body 2, to give suilicient pitch to the unloading cables 6 (see dotted lines, Figs. 2 and 3.), to discharge a load from said car body 2. Standards 5. rest upon the Hoor of the car body 2 and are rmly 'secured against one 'side thereof by clamping members 7, each consisting of a sleeve 8, engaging the inner sul" face of the car body and a cam lever 9,'said Cain lever being pivotally-connected to a lug 10 resting upon the upper edge of the car body an formed integral with sleeve 8 through which a standard extends. Standards 5 are bifurcated at their upper termishaft 12 upon which the upper ends of the unloading cables 6 are wound, the lower terminals of said cables being attached to hook members 13 adapted -to be removably-.secured to the opposite side of the car body Each hook member 13 'isprovided with ,a setscrew 14e adapted to engage the `underside of the angle-bar 2a, extending-around the upperI margin of the car body 2. Shaft 12 is pro-g vided near its ends with two 'fixedly-mount ed hoisting drumsl, upon which the upper ends of a pair of hoisting cables 16 are` wound, said hoisting cables extending around guide pulleys 17 and toward one end of the car where they are attached to a hook 18.v

Shaft 12,is`in two pieces adjustably connected by a sleeve '12b and set-screws 12e., Each lguide pulley- '17 is journaled on a; bracket 19Which hooks -under the adjacent,v sill 4 of the car body 2 and is provided-with? a set screw 20 'to saidsill.

In practice, when the car is to be loaded with logs, brush, poles, or the like, the hoisting cables 6 are slackened suiiiciently to lie against the interior portion of the sides and floor of the car body 2 and the load is placed upon said hoisting cables asshown on Fig. 2. Motive power in the form of a team or an engine is then attached to hook 18 which is drawn forwardly in the direcwhereby it is firmly secured Patented' renza, 1914:

.nais 1.1, in which is removably niounted ation of arrow a Fig. 1. This operation un- Winds the hoisting cables from the drumsv 15, which are rotated thereby and in turn rotate `the shaft 12 which winds the unloading cables 6 thereon until the same assume the inclined position indicated by the dotted lines, Fig. 2, which is sufficient to discharge the load to one side of the car track. Should .it be desired to discharge the load some little distance from the' car track uprights 21 are placed againsd that side of the car body opposite the side to which the standards 5 are secured. As the load is raised the pressure thereof upsets the uprights to the inclined position causing them to actas skids in conducting the load clear ofthe track. y

' When desired, the apparatus can be readily frernoved from the car after loosening the clamping members 7, the hook mem` body.

In the'aioed form disclosed by Fig'.

5, the construction of the apparatus is substantially the same as the preferred form, except that the clamping members and the hook members are adapted to t the Wooden body of a car instead of a'steel body.

Referring in detail to said modified form, 2a indicates thewooden car body which is reinforced by Wooden sills 4a.

5a designates lthe standards which are secured to one side of the body 2a by cla-mp,- ing members 7a. Journaled in the upper portion of standards is a shaft 12a pro- .vided with hoisting drums 15a.

'6a designates unloading cables attached at their upper ends to shaft 12a and their lower ends to hook members 13, adapted to be secured to the adjacent sill 4a. It is t deemed unnecessary to show the other parts of the apparatus on this ligure as they are .clearly shown on other figures of the dra-W.- 1n s.

Ida'ving thus described our invention, what we claim and desire to secure by Letters Patent is l. In combination with a carbody, standards vresting against one side and the oor of said body, clamping members to removably secure said standards in position, a shaft mounted upon said standards, unloading means secured to said shaft and the opposite side of the car body, land means to rotate the shaft to Wind said unloading means thereon until inclined sufficiently to discharge a load from the car body.

2. In combination with a car body, standards secured to one side of said body, a shaft mounted upon said standards, hook members 'secured to the opposite side of the car body, unloading means secured atone end to the shaft and at its opposite end to said hook members, and means to rotate the shaft to wind said unloading means thereon until inclined suliciently to discharge a load from the car body.

3. In combination with a car body, stands` ards secured to one side of said body, a shaft mounted upon said standards, `unloading means secured to said shaft and'the opposite side of the car body, hoisting drums mounted upon said shaftto rotate the same, cables to rotate'said drums to wind the.un loading means upon the shaft until inclined suiiciently to discharge a loady `from the can. body, guide pulleys for said cables, and brackets secured to the car body andupon. which said guide pulleys are mounted. In testimony whereof We afiix our signatures, in the presence of two Witnesses. i
